# SketchVideo: sketch-based video generation and editing
<!-- Provide a quick summary of what the model is/does. -->
SketchVideo aims to achieve sketch-based spatial and motion control for video generation, and supports fine-grained editing of real or synthetic videos.
## Model Details
### Model Description
<!-- Provide a longer summary of what this model is. -->
SketchVideo achieves sketch-based video clip generation (~6 seconds, 8 fps) based on text prompts, one or two keyframe sketches (at arbitrary time point).
SketchVideo also achieves sketch-based editing for video clips (~6 seconds, 8 fps) with the same inputs.
This model was trained to generate 49 video frames at a resolution of 720x480 given a context frame of the same resolution.
- **Model type:** Video Diffusion Model
- **Finetuned from model:** CogVideo-2b (720x480)
### Model Sources
<!-- Provide the basic links for the model. -->
For research purpose, we recommend our Github repository (https://github.com/IGLICT/SketchVideo), <br>
which includes detailed implementations.

## Uses
Feel free to use it under the Apache-2.0 license. Note that we don't have any official commercial product for ToonCrafter currently.
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
<!-- ### Direct Use
We develop this repository for RESEARCH purposes, so it can only be used for personal/research/non-commercial purposes. -->
## Limitations
<!-- This section is meant to convey both technical and sociotechnical limitations. -->
- The generated videos are relatively short (6 seconds, FPS=8).
- For two keyframe sketches, they should have consistent content.
